For running your apps there are two possible ways:

  • Running on the emulator
  • Running on a device

Running on the emulator

Emulators are Android Virtual Devices (AVD) that we need to configure to run our Android apps.

Step 1

Open the AVD Manager as in:

Step 2

Click on the New Button to add a new device, and configure your device settings.

Step 3

There will be a result window showing all the configurations you had chosen on the previous screen.

Step 4

Press "Ok" and you will see your device listed in there and now you can close this window now.

Step 5

Run your Android app project from Eclipse and if there is only one AVD configured it will automatically deploy the app to it else a window will appear to choose your AVD. The Emulator will start.

Running on the Device

An Android app can be directly deployed on the Android device, for this a few configurations are needed.

Step 1

Set the application in the debug-able mode by setting the android:debuggable attribute of the <application>element to true. For ADT 8.0 this is done by default. (In our ADT we do not need to perform this step.)

Step 2

Enable USB debugging on your device.

For Android 3.2 or older go to Settings > Applications > Development and enable USB Debugging.

On Android 4.0 and newer, it's in Settings > Developer options.

Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About in the phone and tap Build number seven times. Return to the previous screen to find the Developer options.

Step 3

Install USB drivers for your device so that the computer recognizes your device.

Step 4

Once set up and your device is connected via USB, install your application on the device by selecting Run > Run (or Run >Debug) from the Eclipse menu bar.

Cheers.
